Fire up a command prompt, pass AutoRest.exe some parameters and like magic you have an instant library in your language of choice to add to your app.
For example, the following will create a C# library and place all object in the AwesomeApp namespace
AutoRest.exe -CodeGenerator CSharp -Modeler Swagger -Input swagger.json -Namespace AwesomeApp
To use the library out of the box, add the Microsoft.Rest.ClientRuntime nuget package to your project or simply steal the model objects and roll your own wrapper around HTTPClient.
As the tool is a simple console app, it can be added as a custom build step
